This invention relates to an electric cigar lighter with removable heating wire carrier, the heating vwire being of such dimension that it can be suiciently loaded with heat in 5 order to permit of using the lighterse arately "from the Source of current. The nownA devices of this type are'composed of' a great number of parts, they are consequently expensive and not very secure in working or the .heating body is'not visible from the outside stl) that an unnecessary overheating. takes p ace.

One obj ect of the invention is the provision .of a supporting base having terminalconnections` and a bodily removable heating and lighting unit, movableA into and out of engagement with the base by a sliding movement in a plane arallel to the outer face of the base and pre erably from above, whereby the two cooperate to hold the unit assembled within the base so that they cannot readily become disassembled through jars or acci-l dentally, thus making the device a very desirable one for use in motor cars.

' Another object of this invention is the provision of a cigar lighter having a support and a detachable unit-carrying member, each of which is provided with an axial terminal and vone of which terminals AA is spring-tensioned .35 glow of the unit, when energized, is readily observed and which, due to the surface area of the unit and the manner of mounting, will retain said glow suiciently long after'the carrier is removed from the base to permit the lighting therefrom of several cigarettes or V cigars, thus making the device especially desirable when more than one passenger in a motor vehicle desires to smoke. l

According to the invention, a: fiat boxshaped heating wire carrier is removably to assist in holdin the members interengaged.

. i An embodiment `of the invention is shown,

.by way of-examle, on the accompanying drawing, in whic Fig. 1 shows the electric ignition body in section and in front elevation.

Fig. 2 shows in front elevation and in vertical section the switch which serves as current' supplying socle.

Fig. 3 shows in front elevation and in vertical section the ignition body inserted in the switch-socle. 'v

A is the casing for the cylindrical box-V shaped heating wire carrier or bowl andv oi" which the side wall is formed of electric conducting material. B is' the heat insulating 6 5 mass and D is .the heating spiral. The carrier or bowl A is open at its forward end and the heat insulating mass B tapers from said open 'end toward the rear end of the carrier or bowl. The heating spiral D is'located at 70l the-rear end of carrier or bewl A and thus not only is visible through the open -forward lend of the carrier or bowl when the carrier bottom plate formed of non-conductive ma 8o terial and designed to insulate the heating spiral. An electric contact K is carried by the rear vwall of `the cylindrical box-like casing A concentric with the side wall of the 'latter andk is connected to one end of the S5 heating spiral D. The other'fend of the heating spiral D is connected to the side wall of the casing A. F'is the contact casing, `formed of electric conducting material, lfor the boxshaped heating spiral carrier. are bars of l electric conducting material on the contact casing, which form a frame. K is `a contact button of electric conducting material eX- tending through the front wall ofthe contact casing but insulated from the latter and which serves for establishing the connection with the one pole 'of the current lead, the other pole being the mass of the casing. This contact button K'is acted upon by a blade spring G carried by but insulated from the rear wall of the contact casing and which serves for securely holding the heating spiral carrier in the casing, the other end of said sprirlrg G serving, to maintain the press button normally in the switched out position. When the press button is pushed in it presses the lower end of said blade spring G against the contact plug J carried by but insulated from the'rear wall of the casing whereby the circuit is closed. One pole of the current lead is connected to the mass of the contact casing F and the other pole is connected to the contact plug J.

The operation is as follows The heating spiral carrier is inserted into the frame formed by the bars L and held in this position by the contact button K against the contact K of the heating spiral carrier A under the action of the spring G. If the press button H is pushed in the circuit is closed and current iows from the contact plug J through the spring G and the pressure contact K and contact K intothe heating spiral and thence back through the casing.

The heating spiral D being rvisible from the outside it can be seen at once when the heating spiral has been suiiiciently heated whereupon the press button H is released. rfhe heating spiral carrier can now be removed from the casing and used for igniting a cigar.

I claim 1. Electric lighter for cigars comprising in combination a heating spiral carrier in the form of a iat box, a contact casing, a guiding frame onrsaid contact casing for holding said heating spiral carrier so that the heating spiral is visible from the outside, a pressure contact in theupper part of said casing, a press button in the lower part of said casing, a contact plug in the lower part of said casing opposite said push button and a blade spring fixed in said casing so that its upper end presses from behind against said pressure contact and its lower end against said push button, said blade spring serving as contact between said contact plug and said pressure contact when said push button is pushed in.

2. An electric cigar lighter, including a base and a detachable heat-unit-carrying member,'cooperating electric terminals carried by the 'front face of said base and the rear face of said member and adapted to be engaged when the member is attached to the base, andl cooperating circular attaching means carried by the base and member respectively, one ofsaid attaching means having an opening in its periphery through to contact with the terminals of the base, and

cooperating circular attaching means carried by the support and member, respectively, one of said attaching means having an opening in its periphery through which the other attaching means is insertable and removable by relative sliding movement between said support and member in a plane parallel to the face of the support for securing said member to and detaching it from said support and moving the terminals of the base and member into and out of contact.

4f.' An electric cigar lighter including a support adapted to be held with its forward face in a substantially vertical plane and hav- Ving on said face a central terminal and a terminal spaced from said central terminal, a heat-unit-carrying member having terminals to correspond to the terminals of the base, and cooperating `circular attaching means carried by the support and member respectively, one of said attaching means having an opening in its periphery through which the other attaching means is insertable and removable by relative sliding movement of said member and support in a plane parallel to said face ofthe support.

5. An electric cigar lighter, includingfa base member, a substantially circular plug member, cooperating spaced electric terminals carried by said base and member, and substantially circular inter-engaging supporting means carried by the base'and plug members, the supporting means of one of said lmembers having an opening in its periphery through which the supporting means of the other member is insertable and removable, whereby movement of the plug parallel to the face of the base in one direction will cause engagement, and a like movement in the opposite direction will cause disengagement of said means, the terminals of said base and plug members being so arranged as to aline in any position of interengagement of said supporting means.

6. An electric cigar lighter, including a substantially circular base, a substantially circular plug, cooperating electric terminals carried by said base and plug, and cooperating concentric inter-engaging supporting i front of the base part said-socket having an y n. allel to the front face of the stationary means carried by the base and plug whereby movement of the plug in a parallel plane to the base in one direction will cause engagement, a like movement in the opposite direction causing disengagement, two of the coacting terminals being coaxial and the other coacting terminals being such as to engage when the coaxial terminals are in engagement, and one of said terminals being tensioned out Wardly to normally hold i the plug against accidental displacement.
